This function allows the technician to adjust the water conductivity threshold. This may be required
after a change of sensor and should be checked after a controller or software change.
Up to 2008, all units used the water sensor to detect both water quality and water level. In 2008,
all units were upgraded with a float in the chamber to detect level, which allowed the sensor just to
monitor quality.
The default conductivity setup is as follows:
Note that these settings should NOT be changed to suit water used as damage MAY occur
to the components of the STATIM.
Units with sensor but WITHOUT float
– LL.L (Lower value threshold / No water threshold. Values lower than this triggers
“Refill reservoir empty waste bottle” error) = 0.3uS
– HH.H (Upper value threshold / Bad water quality threshold. Values higher than this
triggers “Water quality unacceptable” error) = 10.0uS
– G.GG Water conductivity circuit gain. Default value 1.00
Units with sensor and WITH float
– LL.L (Lower value threshold / No water threshold. Values lower than this triggers “Refill
reservoir empty waste bottle” error) = FLOAT
– HH.H (Upper value threshold / Bad water quality threshold. Values higher than this
triggers “Water quality unacceptable” error) = 10.0uS
– G.GG Water conductivity circuit gain. Default value 1.00
On entering the Conductivity setup sub menu, the first digit will be highlighted and can be
changed as follows:
The flashing value indicates the currently selected field.
The values shown on the screen are as follows:
xx.x – Actual water conductivity in uS (micro-Siemens) as read by the unit software.
NNN - Water conductivity in ADC (Analog to Digital converter) counts (0…255)
y.y - Water quality in ppm (parts per million) as read by the unit software.
LL.L - Lower value threshold / No water threshold/Float status.
HH.H - High value threshold / Water quality threshold.
G.GG - Water conductivity circuit gain
Note that xx.x, NNN and y.y are for information only as measured by the unit software and
can not be changed.
